Thomas Jefferson, the 3rd President, was part of the deleted scene mentioned above. His quote "I have sworn eternal hostility against every form of tyranny over the mind of man." was remembered by Starfleet for the quote that appeared on the dedication plaque of the USS Yamato in TNG: "Contagion". This dedication plaque was not readable in any canon material.

Some Star Trek books list that the United States still exists as a political subdivision of United Earth as late as the late 24th century, and is still led by a President.
